No, The mileage is stored in the BCM not BCU ... Everytime you reset yur oil life it is an automatic reset so they have no other way of telling you put the stocker back in, other then the fact it will be clean as a whistle

Solstice guys have been doing this for quit some time now not sure if you knew ...

If you are sick of waiting and wan't the same result

Step 1: contact GTPPrix a CSS member

Step 2: Buy ECU around $200.00

Step 3 Replace original with new ECU

Setp 4: Tune with Trifecta (250$) or HP- Tuners Custom tuned. $450.00+

So if it is just a tune you are after for an easy 40HP increase under 500 dollars and no warranty voided ... You can run all stock parts tuned if you want but its up to you .

 

if the last mechanic I dealt with at the dealership tried to read an ecu and get into the o/s he would just end up poking himself in the eye or breaking something. He forgot to tighten my valvestem properly, better yet crack the secret code on the ecu... I bet he couldnt spell ecu..There is nothing in the warranty that say's you can't buy spare parts for your car.

 

Thats what I am saying. If your dealer is that big of a dick I would just find a dealer who is down for whatever... If you blow it up using nitrous and other mods I wouldn't try to get any service work because they will be able to tell what happen and it is your fault. Don't be stupid with how you choose a dealer and you should be just fine. I know some of us aren't fortunate to have mutliple dealers in the area they are in but you pay to play .... get a tow to a dealer you know it down and you talk to the service manager. Who cares if they have to compare the tune with one on the tech2. If yo swap ECU's the right way everything will be fine. This doesn't mean you should just tune it by yourself custom and blow it up and expect GM to fix it .. Simply for warranty work or anything else recalls etc that may require an ECU update you don't want to have a tuned ECU with the incompatible HASH file.

 

I won't be surprised if GM came out with a manual for technicians like Chrysler did for the Neon SRT4's etc though. I haven't seen it in a few years, but basically they sent out a manual on how to spot common mods and common failures relating to the mods. You can bet they were cruising forums looking for ideas on that document.

**** with the system enough, and it might fight back

EDIT: Found a copy of the old Chrysler document on google: http://www.midatlanticsrt.com/srt/do...ftermarket.pdf

FWIW, I'm letting all you guys on the Solstice and CSS do the modding for me... and then let me know what breaks over a couple years hehe. I'm pretty sure the Cobalt stage kit will eventually come out, and if I had to guess (as others have) its due to CARB/EPA certification. If it doesn't come out, oh ****** well. I'll just buy HPTuners and call it a day after my bumper-to-bumper warranty expires. By then they'll have a lot more figured out on the Bosch ECU's too. This is my daily driver and I really could care less if it runs 12's or not.

 

You sure do post a lot in here for someone that clearly doesn't care about the GM upgrade. You've given your 2 cents numerous times, thank you.

 

you would have to be a dumb ass to leave that stuff on your car... I mean read it, they pretty much tell you an exhaust and intake are NOT going to hurt the durability, they are just "signs they may have more mods"... if you leave a large intercooler, aftermarket turbo, piggyback unit, or nitrous on your car and try to get warranty work done, you DESERVE to have your warranty voided, you are a dumb ass

 

Did you notice the one part of the Chrysler PDF? Where even back on the older SRT4's they could compare milage in the ECM vs. the BCM milage to determine if the Neon owner was swapping ECU's around. Our cars are 5-6 year newer designs... so it seems likely that GM would also have this same functionality but I've seen threads where people claim that's NOT the case.

And your right... the technicians see an intake and are like if he has an intake, maybe he has this.. and it snowballs. That might lead to the tech2 coming out and ruining your day.

I'm a n00b to modern GM's, so kick me in the head if I'm rehashing stuff ... I'm honestly not trying to a pain in the ass. The last GM I owned was my '96 Z28 and it was far less savvy at detecting mods

 

I had a '96 Z28 in '01-'04 as well... OBD-II was new to that era

also, I agree that it seems they can detect the discrepancy in mileage, all I plan on adding is the GM LFN upgrage kit, for this very reason. I was going to add exhaust, etc., but they gains won't be worth the potential warranty loss, the GM LNF upgrade is NOT designed for Offroad use, and it will be covered under the original powertrain warranty, so if you don't play with fire, you won't get burned... I do have an open cone intake on it, but i'll be putting the stock air box back on when it goes in for work the upgrade installation(and any future warranty work), lol

 

L O L !!!! I'm doing the same thing! (Not getting married, did that 10yrs ago) but I'm hoarding a bit of $$ for when this comes out. I've got $1k stashed in case they require a bit more...

This comment cracked me up though...

 

The tech 2 only reads the bcm for milage, thats how it works. Even if your dealer is good enough to have the MDI system it still only reads the BCM for milage, but still has the ability to upgrade any computer on your car. Now while all this is true the SS's also have the ability to throw an "abuse" code, but i cant rember the paramaters for that to happen.

 

I'm going to put on a wifebeater and start slaping my Cobalt around, see if it sets the code.

 

lol im just saying when i rebuilt trans for a dealer in maryland there was a special spot in the pcm that i belive the tech 2 could reach for the code to void the warrenty

 

I'm sure using any of the competition mode stuff might not help. The warranty and owners manual pretty much says: use that mode, and you're f'd in the a come service time. Its kinda like the new GT-R. Just don't put the stupid feature there if all it does is void the warranty.

 

I read over the manual looking for that exact thing and couldn't find anything... and its definitely not in the warranty papers, once again I went over them with a fine tooth comb, it mentioned racing, etc... but no competition mode voiding the warranty, are you sure you aren't confusing "competitions" with competitive mode?

if you abuse any car, they are going to void your warranty, but they won't be like "ok, here you engaged Competition Mode, no warranty for you"... like the GTR and turning off your VDC...

 

Crap I put the manual back in the car today, but look in the sections where it tells you how to use traction control, competition mode and all that. In my 2009 model it says to refer to the warranty guide before making use of those modes.

Perhaps me saying your warranty will be void by using them was a bit heavy handed, but I'm sure it wouldn't help any warranty claim if god forbid anything broke around the same time you used them.

EDIT: I went on the GM owners website and looked at the manual online and it says this:

That leaves a lot open to interpretation on both sides.

 

yeah, that is called ABUSE

that has nothing to do with competition mode, and as it says, traction control being off is also mentioned... if you abuse the car in any mode they are going to void it... whereas, the GTR DETECTS the VCD being turned off and at that moment, the warranty is voided, there is nothing like that with competition mode on the Cobalt

 

Weren't they supposed to release it some time i august???
idk i'm just assuming but its pissing me off though
plus what's the HP gain??

 

last August? no, it wasn't even confirmed until what, October?

 

first quarter.......which is gonenow
315hp @ cranck??? and 330 lbs ft crank?

 

Here are the numbers!!!!!
Stock GM Tune
260/260

Stage Kit NOT RELEASED
XXX HP/ XXXTorque TBD??



The end!

 

Here are the numbers!!!!!

Stock Cobalt SS/SC
205hp/200trq

Stage 2 Cobalt SS/SC RELEASED
245hp/220trq

he he

 

Man. almost 750 posts over a kit that adds 20-30 whp and 60 wtrq. Just get a good tune and call it a day. GM will not warranty your stage tune car if you beat on it and break something so what is the difference?

 

No one knows the exact numbers yet so don't go filling the thread with uneducated guesses.

We will know when we know.

 

i thought kit was quoted from somewhere important inGMPP that is was going to be 315 crank hp and 330 crank torque????

obviously we dont know till its here but i thought that was a givin

 

I wouldn't say he is is uneducated. And if he is off by +/-5hp, big deal, don't take your frustration of the kit not out yet on him.
